A reel l3 .is removab lyhpositioned upon1 each end o fthe spindle 1l"southat each, cdmsj partmentgofthecasing. contains areelmand each .reelihas. the large, stiff} insulated IWire- 1e Wound thereon,'one-strand of,the;wire

Th'eseireels are of, suchilengthllas. to extendwill be 7, prevented fromturning; too. fre,

and bearing against the adjacent end of the adjacent reel or spool. Thisbrake element preferably consists of. a resilient strip of metal withone end fastened against the inner face of the door and with its otherend extending inwardly to engage the adj cent spool;

The top wall of the casing 5 is provided with openings in which arefitted porcelain bushings 16 through which the wire may be threaded forconvenience in dispensing the wire from the spools as required. Thesebushings are located in avertical plane to one side of the spindle 11 sothat the wire will pass outwardly through the casin in a ready and mostdesirable manner. Also, to suit the requirement of special cases, thewire may be taken out through one of the side walls of the casingthrough the pro vision of further porcelain bushings 16 se cured insuitable openings in one side wall of the casing in a horizontal planeabove the spindle 11. In order to permit convenient carrying of thedevice from place to place, the top wall of the receptacle has a handle17 suitably hinged thereto by means of a retain ing plate 18 which isriveted or otherwise secured to the casing.

In operation, the end doors 6 are released ind swung downwardly so as topermit ready access to the ends of the spindle 11, and then the requiredspools of wire are placed upon said spindle in the compartments 9 and10, the end doors 6 then being swung upwardly and latched in closedposition, after the ends of the wire have been threaded outwardlythrough the desired ones of the bushings 16 or 16. The desired amount ofwire is then readily used by removing the wire from the casing by simplyexerting a pull on the outer end of the wire. It will be seen that whenthe wire has been entirely used from the spools, they may bereadilyreplaced by new spools containing full amount of wire.

From the foregoing description it will be seen that the wire will bereeled off of the spools as needed in a straight and natural position sothat the wire cannot become twisted or tangled and as the unused wirewhich is outwardly of the casing may be readily reeled thereinto, thereis no danger of causing damage to or soiling of the unused wire whencarrying the device from place to place.

Minor changes may bemade without departing from the spirit and scope ofthe in vention as claimed.

It will be seen that the chambers 9 and 10 may be formed of separateunits such as would be produced if the device in Figure 1 had its top,bottom and front and rear walls severed in a vertical plane between thetwo thicknesses of wall of the partition 8 with the spindle 11 alsosevered in this plane. With such a construction the machines may beplaced on the market in single units holding only one spool of wire, andif the user of the device desires to use a double unit he can bolt twoof the single units together.
